TXTextControl.TXTextControl.ImageExportFormat Property

Determines the format used if an image is saved. This is the number of the filter in the string
returned through the ImageExportFilters property, beginning with number one. If the
ImageExportFilters property is used to initialize the
Filter property of a Common Dialog Control, the FilterIndex property of the Common Dialog Control can be
used to set this property. The ObjectCurrent property
determines the image.
